To provide an air conditioner that can ensure the starting-up of a compressor even when both of the ambient temperature and the compressor temperature are high.SOLUTION: In an air conditioner, in the case of "ambient temperature≤T1" or "compressor temperature≤T2" (NO for S1 or S2), a compressor is started up in a first start sequence (S3), and in the case of "ambient temperature>T1" and "compressor temperature>T2" (YES for both S1 and S2), the compressor is started up in a second start sequence (S4). The first start sequence is a start sequence in which vibration and noise at the starting-up are effectively suppressed. The second start sequence is a start sequence that ensures the starting-up of the compressor even in an overload state.SELECTED DRAWING: Figure 2 【課題】外気温および圧縮機温度が共に高い状況でも圧縮機の確実な起動を行うことのできる空気調和機を提供する。【解決手段】空気調和機は、"外気温≦Ｔ１"または"圧縮機温度≦Ｔ２"の場合（Ｓ１またはＳ２がＮＯ）は第１の起動シーケンスにて圧縮機の起動を行い（Ｓ３）、"外気温＞Ｔ１"かつ"圧縮機温度＞Ｔ２"の場合（Ｓ１，Ｓ２が共にＹＥＳ）は第２の起動シーケンスにて圧縮機の起動を行う（Ｓ４）。第１の起動シーケンスは、起動時における振動および騒音の抑制効果が高い起動シーケンスである。第２の起動シーケンスは、過負荷状態においても圧縮機の確実な起動が行える起動シーケンスである。【選択図】図２
